OpenAI's corporate security team sent a notification to employees stating that an unidentified individual approached Altman's residence around 3:45 AM local time and threw a Molotov cocktail. The device landed nearby and was extinguished; it was explained that there were no injuries and damage was minimal.
Subsequently, near the OpenAI headquarters in an area referred to as MB1, security personnel approached an individual matching the suspect's description. This individual reportedly made threatening remarks regarding the building.
According to a statement from the San Francisco Police Department, they responded to a fire investigation in the North Beach district around 4:12 AM. The outer gate of the residence was burned, and the suspect reportedly fled on foot.
Within an hour, police located an individual identified as the same suspect outside the OpenAI office. The man, aged 20, was arrested in flagrante delicto.
Kayla Wood, a spokesperson for OpenAI, said that fortunately, no one was injured. She stated that they are proceeding with a cooperative investigation with the police.
This is the latest instance of threats against OpenAI's offices and staff. In November of last year, the office was closed due to threats from activists, and in February 2025, protesters were arrested.
